At the invitation of the Consolidated
Railway Telegraph Company of this city
large party Of electricians and others
made trip upon the Lehigh Valley Rail
road on Thursday, OCTOBER 6, to inspect
the operation of the system of train teleg-
raphy in use upon f1fty-four miles OF, the
road.
The system, due to Edison, Phelps,
Gulilsnu, Smith and others is we'll known
in iis main features to our readers, but
certain notifications have been intro
! duced which have greatly improved it's
efficiency, 80 that SO 1t now stands all the
| diff ulties hereto ire encountered may
be said to be entirely overcome.
In the FIRST equipment on the Lehigh
Valley Railroad the inductive receiver on
| he car consisted of coil of mauy turns
of wire wound around the car, and the
| Iipe conductor was an insulated wire laid
along the track. While this system Leaf
| little to be desired, it involved some ex-
pense which is avoided by the method
used at present. This consists in tn
employment of the roof OF the car, Wherr
such is available. as static receiver. and
| the line is Ell OIQlGaIy WIG siA aO@ uPOH
poles near the track.
With the present system the roof OF the
car is, in most cases, available, and car
can be equipped ready for work in re-
markable short time. All that 1s neces-
sary is the attachment of g wire to the
| roof, another to the swivel plate OF Cal
truck for the ground, and the insertion
of the instruments in the circuit thus
| formed. Such was the arrangement oi
| the directors car, which was attached t.
| the special train on the excursion, ard
the whole equipment did not occupy ter
| min utes.
The system es it exists to-dsy, briefly
stated, consists mainly in the Use OF the
''short pole" telegraph lie extending
along the side Of the railroad track .
about distance OF eight or ten feet from
the lire, the poles being much snaiisl
than ordinary telegraph poles, and from
ten to sixteen feet high. At their top l.
placed an ordinary glsss or porcelain In
sulator, s;rurg upon which is single
galvanized steel Cor irony telegraph wire
about No y, American gusge. As re
marks d before, the metal roof OF the Car
wherever prsctica lie, Is employed SO N
inductiye receiver Of the Car, but where
no metal roof exists al iron or brass roc
or tube half sn inch in diameter is en-
ployed, placed under the caves OF the car
From the roof the wire passes to the In
struments, and then TO the wheels OF tn
car.
The operators equipment is quite SIM
pie, and consists merely OF 8 small taolet
} to which the key, the coil and the o1zze,
are attached, and With just sufficient TOT
surface 20 hold telegraph blank con
venienty. TIE battery employed Is IN
closed in box, and can be placed oesid
the operator, or csn be slowed sW.y IL
one of ths closets CT the car. The opera
tor seats himself in chair with his in
strument and clip for holding message:
he is to send, both on little board whic
rests in his lap 4 battery OF tWelv
small cells is employed in circuit With II
primary Of the induction coil, although /
is stated that communication can be KEEP
up with two cells.
The arrangement ct the terminal SIS
, ton, so far as the induction circuits an
instruments are concerned, is identlca
with that on the car; but in additiol
, there is supplied Morse arrangement
, by means of which the line can be use
| for the transmission of ordinary Mors
business. The cost of equipping s rsil
, road with this system depends somewhs
on the character Of the roadway, nssrnes
